Windows 7和Vista UAC – 以编程方式请求C#中的提升

我有一个程序,在极少数情况下只需要提升到Admin,所以我不想设置我的清单以要求永久性提升。

我怎样才能在我需要时以编程方式请求提升?

我正在使用C#

WindowsPrincipal pricipal = new WindowsPrincipal(WindowsIdentity.GetCurrent()); bool hasAdministrativeRight = pricipal.IsInRole(WindowsBuiltInRole.Administrator); if (!hasAdministrativeRight) { RunElevated(Application.ExecutablePath); this.Close(); Application.Exit(); } private static bool RunElevated(string fileName) { //MessageBox.Show("Run: " + fileName); ProcessStartInfo processInfo = new ProcessStartInfo(); processInfo.Verb = "runas"; processInfo.FileName = fileName; try { Process.Start(processInfo); return true; } catch (Win32Exception) { //Do nothing. Probably the user canceled the UAC window } return false; }
